My yinvention'relates to rulers, more parlticularly to desk rulers forruling with pencils or writing pensyand provided withfiducial .rulingedges .for such purpose, themain object of my invention being to providean improved instrument ofthis ycharacterI which will vembody certaindesired features of simplicity, efliciency and convenience, and whichwill afford la practical, inexpensive advertisingmedium. L

An object of my invention Ais .to provide a' ruling instrument.characterized `by having means in the form .of replaceable inserts for ycarrying advertisements, calendars, combinations thereof, or any printedor Written matter which it may be desired to discard and replace fromtime to time.

A further object of myinvention is to"pro vide a ruling instrumentin'ywhich the means vfor carrying thereplaceable inserts .willA also serveasmeans forholding the lidu'cial ruling edge Aso spaced .from the lpaperth'atlthe ink falling fromv a writing 'pen' will not ybe spread andVblurred over .thefruledlines Another object lof my invention. is toy)provide a frame construction containingk the replaceable 'insertfea-tures and to lsoarrange the frame construction that it may ,beemployed either as an attachment for the or-` dinary desk ruler'or as acardholder capable offbeing attachedeto' a trunk, shipping ca se,

or the like. y l Other objects will appear hereinafter. rlhe invention,consistsin the combinations and arrangements of parts'hereinafterdescribed and Claimed.. f

.1 to 4, inclusive, wherein by way of examplekI have illustrated apreferred embodiment ofmy invention, the numeral l1.y designates sakbody element made of L any suitableshe'et metal Aand provided witha''straightor rul-` fing edge 12 :withwhichupon the opposite :i:

faces [f :the body lelementfaare associated :hnear scales 1'3 .and 1.4-,respectively, A'sai-d. i scales .preferablyreading in lopposite ldirecltions vand differing .fromeacli other in ,that

they Vcontain different arrangements `vof inches or Yfractional.partsthereof. :The side l5., opposite .the straight edge 12, ismade vWith-'anintegralflangeA 16 which is bent `fiat- Wise over one face oflthe bodyelement. `In

a similar manner the opposite-ends 17 are provided with integraly`ianges 18 which are 'bentiiatwise .over the same'lface of the bodvelement. lBack a distance vfrom the vlinear scales, `integral flangesI19 are struck-from the stock and bent flatwise over the body7 elementand toward the Hange- 16. The flanges, thus produced, are on the sameface of the body element, and provide confronting channels 20 for thereception of a strip 21 which may have any suitable matter'- ends. aremadewithintegralflanges 33 and i.

so that it may be readily applied or removed through ways or openings24, preferably producedvby omitting the flanges for this purpose. Bythisarrangement the :bendable strip 2l may be'removed and replaced fromtime to time.

According to another important feature of my present invention, theinturned flanges 16, 13 and 19, serve as rests for supporting the bodyelement with the straight or ruling edge 12 raised from thepaper tofberuled; In view of this provision, an ordinary writing pen may beemployed 'in connection with the straight edge 12 without spreading theink and blurring the iuled lines.

In Figs. 5 to 8, inclusive,fI show a modified construction whichA iscapable ofruse as an attachment for an ordinarydesk ruler 25. In thisconstruction, the sides and ends `'of the body element 26 are maderespectively Vwith inturned side and end flanges 27 and 28 so as toproduce confronting grooves for theV reception and retention of aflexible strip 2,9. As in the previous form, the side flanges areinterrupted to provide opposing ways 30 through which the advertisingstrip may be entered or removed. The body element 26 is provided withsuitable openings 31 for the .reception of screw elements 32 ay whichthe bodyzelement may be secured in place upon the ruler 25.

AIn lFigs. 9 and l0 I show another modiication suit-able for use asA `anattachment.

In this embodiment, the construction vin- 35- cludesa frame 'composed ofopposing sides 33 andV opposing ends 34, which sides and 134:',respectively, for retaining the advertising stripjyThe side flanges33aresuitably linterrupted to provide opposing ways 35 throughl which theadvertising strip may be `applied or removed` In this construction, theopposing sides 33 are connected by.

strengthening webs 36 in which are produced .the openings 37 for the`receptionf of the screw elements by which the attachment may Abesecured to the ruler. By making the de `vice/inthe form of anattachment, it is capable offbeing used not only in connectionV ing fromthe spirit of thel invention.

-inodifications asy come within -the appended claims.

with a Common desk ruler but also in con# nection with a trunk or othercarrying receptacle on which it may be desired to change theidentification card from time to'time. v

. lhile I have illustrated and described the preferred form ofconstruction for carrying my invention yinto effect, this isgcapable ofvariation and modification without depart- I therefore, do not wish tobe limitedto the7 precise details'ofconstruction set forth, but

desire t0 avail myself of such variations and the scope of Havingdescribed my ,invention what'I 'claim as new and desireto secure byLetters Patenti is 1.A A ruler constructioncomprising a body elementhaving a ruling edge; and confronting flanges on said element varrangedto hold an insert in place-thereon, one of said flanges being struck outof the body element'in- `metal bodyelement having a ruling edgeandlinear scales on its opposite faces along said ruling edge; flanges bentfrom .the stock of A the; body element and jointly comprising means forholding an insert in place thereon;

`certain of said flanges being struck out of the stock inwardly of thelinearscales on the yopposite faces of the body element, substantiallyas described.

In testimony whereof I'have signed my name to this specification. j
